Resource Conservation and Recovery Act (RCRA) Permit

Permit History:

In March 1995, NDEP issued a Part B Permit to the Department of Energy, Nevada Operations Office for a Hazardous Waste Storage Unit (HWSU) and Explosive Ordnance Disposal Unit (EODU). The permit was subsequently renewed in 2000, 2005 and 2010. In 2010 NDEP issued a new permit for a Subtitle C landfill herein referred to as the Mixed Waste Disposal Unit (MWDU) and Mixed Waste Storage Unit (MWSU). In 2011 the MWSU, MWDU, HWSU and EODU were consolidated into permit NEV HW0101.  In 2015 NDEP issued a permit renewal for permit NEV HW0101.
